Treatment and study plan

GNS-212-E1

Drug

Subjects who are randomized into this group will take GNS-212-E1 from the evening before colonoscopy to the morning of colonoscopy.

GNS-212-E2

Drug

Subjects who are randomized into this group will take GNS-212-E2 from the evening before colonoscopy to the morning of colonoscopy.

GNS-212-ER

Drug

Subjects who are randomized into this group will take active control drug (PEG3350) from the evening before colonoscopy to the morning of colonoscopy.

Primary outcomes

  1. To evaluate the successful % of bowel preparation before colonoscopy (colon cleanliness) using the HCS (Harefield Cleansing Scale)

    Time frame: on the day of scheduled colonoscopy

    HCS grading of A and B would be classified as successful while C and D would be classified as not successful

Secondary outcomes

  1. Overall rate of bowel preparation

    Time frame: On the day of colonoscopy

    Percentage of test subjects for respective HCS grades

  2. Overall patient satisfaction and compliance

    Time frame: before and on the day of colonoscopy

    Subject questionnaire evaluation total volume, taste etc.
